I bought an Yougo sks new about a year ago and now it shoots as straight as ever but it wont eject the spent round. i have ran probably 2000 rounds through it i would like some help please! Also is their a removable mag out their that is worth buying? I have tried several diffrent stamped steel brands with no sucess. I have seen those tapco 20rd mags but dont want to spend the money just to get the same result, are the worth the $$ ? i have waaay to much ammo piled up to scrap this rifle so help would be nice.
